Induced nuclear activity in galaxy pairs with different morphologies (E+E), (E+S) and (S+S)
Francisco J. Hernández-Ibarra, Yair Krongold, Deborah Dultzin +5
We analysed 385 galactic spectra from the Sloan Digital Sky Survey Data Release 7 (SDSS-DR7) that belong to the catalog of isolated pairs of galaxies by Karachentsev. The spectra c…
Motion planning in real flag manifolds
Jesús González, Barbara Gutiérrez, Darwin Gutiérrez +1
Starting from Borel's description of the mod-2 cohomology of real flag manifolds, we give a minimal presentation of the cohomology ring for semi complete flag manifolds $F_{k,m}:=F…
The cohomology ring away from 2 of configuration spaces on real projective spaces
Jesús González, Aldo Guzmán-Sáenz, Miguel Xicotencatl
Let R be a commutative ring containing 1/2. We compute the R-cohomology ring of the configuration space F(m,k) of k ordered points in the m-dimensional real projective space. The m…
The higher topological complexity of subcomplexes of products of spheres---and related polyhedral product spaces
Jesús González, Bárbara Gutiérrez, Sergey Yuzvinsky
We construct "higher" motion planners for automated systems whose space of states are homotopy equivalent to a polyhedral product space , e.g. robot arms…
